CALLING DEVI Application filed July 555, 1931'].

To all whom it may concern:

Be it known that I, Vfinnmm :lCAIfiLlNG, :1.

citizen of the United States of America, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Ini n-ovcments in Culling Devices, oi. Which'the following is n specification.

My invention has to do with calling devices of the type connnonly employed in automatic and soini-mitmnn tic telephone 5y toms for the pin-pose of operating; diroetivcly controlled switch mechanism und more porticularly to that type fllOWli us two wire or metallic systems in which no ground connection is necessary at the ceiling device for controlling the operation of the direetively emitrolled switches.

The device of ly invention is more ourticulzirly adopted for use in connection u ilh a so-cnllcd two wire system, but with slight modifications of the impulse spring; combi nation it may he used in connectio'i'i with any system Where it is desired to transmit n series of impulses by an operator the ohject of In y invention being" to provide a cell ing device ol this sort which is simple in construetiiim and most positive .in its operation.

One of the :t'entures of my invention is to provide impulse transmitting n'icelninisni which is adnpted to be 'WOUIid up or adjusted upon. the movement of the dial. Then by means of a lever, engaged by the lingo;- when in a finger hold of the dial, upon the compl tion of the dial movement, to unl 1:11 the mechanisn'i for trnnsn'iitting inuiulses. This lever also controls means ton-hold the'diul locked against further actuation until the impulse transmitting mechanism has operuted. Thus the impulse transmitting meehiio nism is entirely out of control of the operatornt'tenthe dial has been completely actuated until the said mechanism has operated.

There me many other features nnd ad: vantages in the device of my 'inventionwhich will be more fully understood by reference to the following detailed description in connection with the accompanying drawings, and the scope of the invention will he more particularly pointed out in the n opei'niled clnime,

The. .i i 18 has the :-;pi'ings 53 Midi :iiate, the spring 51' being eci rip arm \vhiie the spring to restore the gee!" lever 18 ion shown In Fig. 8 iilibfi' means of the shaft 57. The spring 58 which is wouhd around the shaft 57 has one end engaging the stud 3 and the other end engaging the latch 56, thereby holding the said latch under tension against the gear lever 18. The finger lever 60 is fastened to oneend of the shaft 61 which projects be- ,yondthe front plate 1.

g The finger'lever 60 is shown in its normal Position by the full lines indicated in Fig. 5," while the dotted lines indicate its actuated osition when moved by engagement with t e finger when in the finger hold. This finger lever 60 serves several difi'e'rent purposes. In the operation of the device the finger is igiserted in one of the finger holds and the dial revolved until the finger comes into contact with the finger lever in the position shown by the full lines of Fig. 5 and continuing the movement of the dial, the fin er moves the lever 60 into position shown y the dotted lines of Fig. 5'. This movement of the lever 60 first trips the catch 56, then moves the gear lever 18 and gear 17 from the pinion 14 to the pinion 50, also at the same t1mea'ctuatin a stop to engage a slot corresponding to t e selected finger hold to revent a further actuation of the dial. Vi? the lever it moves back to normal as shown by the full lines of Fig. 5, thereby releasing the impulse mechanism by the re- 'moval of the tension of sprin 42 from the anchor pallet and allowing t e mechanism to o erate for transmitting impulses.

,. T e indicator 59 is fastened to the front.

plate 1 by screws as shown. This member 59 ,is not engaged by the fin er unless the operator in moving the dia fails to engage thefinger lever 60. If this be the case the finger lever 60 not bein actuated the dial not stopped and the nger then engages the indicator 59 and the operator knows the device has not been properly operated.

The trip arm 55 which is fastened to the shaft 61 is adapted to engage the latch 56 and move the said latch 56 out of en age- ,ment with the gear lever 18 when the finger lever 60 is actuated. The said trip arm 55, b means of the extension 62 then presses tli e s ring 53 into the position shown in Fig. 7 and the said spring 53 being heavy enough to overcome the tension of the spring 54 forces the gear lever 18 over into the position shown in Fig. 7 when the latch 56 is mo'ved'out of engagement with the said gear lever 18, 5 previously described.

When t e finger lever 60 is moved to its alternate position, as shown by the dotted lines in Fig. 5, the trip arm 55 assumes the.

position shown in Fig. 7 and the spring 42, .iwfliich is fastened to the trip arm 55, en-

ages the stud 40 of the pallet 38 holding t esaid pallet in en agement with the escape'mentwheel 33. his prevents any ophen the finger is disengaged from eration of the gear 17 until the finger lever 60 has been disengaged by the finger and restored to normal when the spring 12 again time is in mesh with the pinion 50 and when the said gear 17 operates, it rotates the said inion 50, actuating the impulse springs. ue to the train of gears connect in the gear 17 with the escapement, the said gear 17 is retarded in its movement by the said connection to the escapement Wheel 33.

The unlatching arm 64 is pivotally mounted on the stud 19 and has the spring 65 resting under tension against the projection 66 of the unlatching arm 64. When the latch 56 is moved out of engagement with the gear lever 18, due to the movement of the finger lever 60, the unlatching lever (34 assumes the position shown in Figs. 7 and 8. This unlatching lever 64 is adapted to move the latch 56 out of engagement with the lever 18 when the said lever 18 is in the position shown in Fig. 8 so that the said lever 18 may be restored to normal after the gear 17 has operated.

Fastened to the bottom of" the gear 17 is the stop 67, this stop 67 being carried by the gear 17 in its movement. This stop 67 is normally in a position indicated by the dotted lines in Fig. 6 and when the dial 9 is rotated thereby adjusting the gear 17, the said stop 67 assumes a position out of engagement with the unlatching arm 64., depending upon the adjustment of the gear 17. When the dial has been rotated the finger lever 60 moved to its dotted position as shown in Fig. 5 and then released, the gear lever 18 and'latch 56 assume the position shown in Fig. 8. When the gear 17 then restores to normal operating the impulse springs, the stop 67 moves along with the gear 17 until it engages the unlatching arm 64 and continuing in its movement carries the unlatchingarm 64 with it, the inclined end 68 of the the latch 56 and moves with the gear lever 18 and the said gear lever 18 is then moved to the position shown in Fig. 1 by the spring 54.

When the calling device of my invention is used in connection with a subscribers telephone for controlling directively operable switches over a metallic circuit, it is desirable to shunt the a paratus of the subscribers telephone wh being transmitted, so as to secure a more efiicient operation of the controlled switches over long telephone lines. To shunt the subscribers telephone apparatus while the impulse springs 43 and 44- are operating,

said arm 64 engages it out of engagement do the impulses are 1.! \x F 5 11 J H w. n. .l. U .1 on 1 W... b 6 .n w u 10 L. d. 1 5 h i m m b 1. Ed 6 m x 1 2 \.1 l L i s 0 q n Z! l x; 1 R m m n 3 1 5 m.
